Seattle’s renter-protection rules are at the center of a lawsuit over a $39 million affordable-housing investment that eventually fell into financial trouble. The 254-unit Addison on Fourth apartment complex, which served lower-income residents, is now in receivership. Its owners have won an appeals court ruling allowing them to pursue claims that the city’s regulations amounted to an unconstitutional taking of their property.
The Washington Court of Appeals ruled Monday that GRE Downtowner LLC may continue its case against Seattle. The company says a series of rental rules—including one requiring landlords to accommodate certain additional occupants without their approval—caused rent payments to fall, led to millions of dollars in losses and made the development financially unsustainable.
Addison on Fourth participated in the federal Low-Income Housing Tax Credit program, which offers tax incentives to investors who provide rent-restricted homes for lower-income tenants. Sean Flynn, executive director of the Rental Housing Association of Washington, said the credits can make these projects appealing to private investors, even though their operating profits are often modest. He is working with GRE Downtowner in its lawsuit against the city.
Flynn described Seattle’s successive landlord regulations as a combination that, in his view, turned a functioning affordable-housing property into an unworkable investment.
Court filings say the development generated positive cash flow between 2015 and 2018. GRE alleges that Seattle’s later rules—covering criminal-history screening, additional occupants, some evictions and relocation payments after certain rent increases—were followed by a steep drop in rent collections. The rate fell from 93.9% in 2018 to 44.1% in 2023, while the property accumulated nearly $5.8 million in operating losses.
After a mortgage default, a federal judge appointed a receiver to take control of the property in January 2026.
Flynn argues that restrictions intended to help tenants can also discourage investment in housing. If developers fear that government rules could effectively take control of their property without a legal remedy, he said, they may decide not to build. He added that landlords should still be subject to regulation, but should be able to sue if the rules go so far that their property rights are effectively taken away.
Ilya Somin, a George Mason University law professor who studies constitutional law and property rights, called the ruling more consequential than a routine procedural decision, while cautioning that its wider effect may be limited. Courts in other states could consider it when hearing similar cases, he said. A possible appeal to the U.S. Supreme Court is less likely.
Seattle is among several major cities that have adopted stronger renter protections. San Francisco has long had rent controls and eviction limits. New York expanded tenant protections in 2024 through its Good Cause Eviction law, which restricts some evictions and lease nonrenewals and allows renters to challenge certain rent increases. Portland limits the use of criminal-history checks in tenant screening and requires relocation payments after some rent increases of 10% or more. Philadelphia has also restricted criminal-history screening.
Flynn says the effects of Seattle’s rules reach beyond Addison on Fourth. He believes restrictions have pushed developers and smaller landlords away from the city, where residential construction was once more visible. In his view, less investment means fewer housing options and, potentially, higher costs and lower-quality homes.
GRE’s lawsuit seeks compensation through inverse condemnation, a legal claim property owners can bring when they believe government action has effectively taken or damaged their property without paying just compensation. The company argues that Seattle’s rules, both individually and together, restricted its property rights so severely that the city should cover the resulting losses.
The Seattle City Attorney’s Office said it was reviewing the appeals court decision and considering what to do next. Chief of Staff Dan Nolte said the city had not yet decided whether to appeal.
Somin said he believes GRE has a strong argument concerning the city’s roommate provision, which limits landlords’ ability to exclude certain additional occupants. He pointed to the U.S. Supreme Court’s 6–3 decision in Cedar Point Nursery v. Hassid, which found that a California rule requiring agricultural employers to let union organizers onto their property amounted to a physical taking under the Fifth Amendment.
Somin said Seattle’s requirement raises a related question: whether landlords can be required to house people who were not part of the original rental agreement and were not screened by the property owner.
